The double tourbillon 30° is the first fundamental invention of Glauber Fauci, which was exhibited at the Baselworld in 2004. This proved the success of the independent studio. Seven years later, the double tourbillon 30° technology won the first place on Concours. International timekeeping. Throughout the competition, the total score of this timer reached 915 points (maximum 1000 points), and the average timing speed was 0.3 to 0.8 seconds per day.
Now, Greubel Forsey will introduce ceramic double tourbillon 30° technology, which is an extremely accurate, delicate and robust timepiece.
The double tourbillon 30° in the center of the timepiece contributes to its extraordinary accuracy. Inside the four-minute cage, a smaller cage equipped with a balance wheel and spring assembly is tilted at an angle of 30° relative to the first cage, and the rotation is completed within 60 seconds. Combining the 30° inclination with the different speeds of the two tourbillons can average out the position errors caused by gravity in all common watch positions (especially stable positions), thereby improving the timing performance.
In the Double Tourbillon 30° double tourbillon technology, four coaxial barrels are connected to a spherical power reserve differential, which can provide 120 hours of chronograph power reserve.
Robert Greubel and Stephen Forsey, inspired by the phenomena of transparency and lightness, are pushing the boundaries of watch architecture to draw onlookers to the symbolic replica Glauber Forsey ( Greubel Forsey) timepiece. This limited edition of 11 timepieces is made of ceramic for the first time, a very rigid material sold in the US market.
The shadow of the impressive blue ceramic case and the light flooding from the sapphire crystal movement. The clock has been redesigned to include these elements, requiring very special expertise and knowledge. Now, it reveals the fascinating sight of two complete suspensions of the dual tourbillon 30° movement.
Transparency has always been an indispensable part of Greubel Forsey’s work. This is particularly evident in the construction of the various versions of the Double Tourbillon 30°Technique-all presenting a panoramic view of the movement architecture. This dual ceramic tourbillon 30° technology further breaks the boundaries of transparency by reconsidering the structure of the entire timepiece to adapt to the special constraints of the sapphire crystal.
The eyes can tell every detail. The small seconds and power reserve indicator in gold are made of blue, which contrasts sharply with the matte main board, reminiscent of sparkling blue ceramics.
The hour and minute hands and the 4-minute tourbillon rotation indicator at 6 o’clock are all immersive structures made of sapphire, allowing light to enter all levels of the mechanism. The hands are hollowed out to further enhance light and transparency. In the mysterious dance that seemed to hang in the air, Double Tourbillon 30° immediately attracted the attention of the audience.
After rebuilding the movement, Robert Greubel and Stephen Forsey met the challenge of accommodating the sapphire crystal element, especially the machining and finishing in three dimensions in order to achieve Grobel ·The unique geometric shape of Fauci perfect copy watches and strict standard sapphire crystal elements.
The watchmakers of the two creators took the movement to the extreme of architecture and created a three-dimensional sapphire bridge. It turns out that it is particularly difficult to achieve this challenge. It is processed from a single piece of sapphire, and its side is polished with different crystal grains. It requires highly professional tools, excellent precision and professional knowledge. The beveled corners reveal a matte finish that contrasts sharply with the polished transparent surface of the sapphire.
Because of this transparency, the entire wheel and pinion that make up the timepiece are exposed to reveal an unprecedented visual experience of the movement structure.
On the dial side, the tourbillon bridge, barrel bridge, differential bridge and power reserve bridge have been removed and remade in sapphire to show the internal mechanism of the timepiece. In order to incorporate these new elements, sports must be reconsidered. In this creative spirit, even the restrictions imposed by screws are considered: the bridge is specially installed to absorb the impact that the sapphire may suffer. Therefore, the board, bridge and mechanical structure are completely new.
On the side of the bottom cover, the three-dimensional gear chain bridge can clearly see the magnificent building below. This unusually large bridge has a multi-layered design with counter holes that allow the wheels to accurately overlap the sapphire. The whole mechanism emits light, rewarding the beholder with a fascinating sight. The lower tourbillon bridge (also made of sapphire) accurately reproduces the steel bridge that originally adopted Double Tourbillon 30° technology, marking a major achievement in sapphire craftsmanship.
This is the first time Greubel Forsey has shown the movement inside a ceramic case, which requires extremely high precision. The material is compacted by pressing and shaped before firing. During the heat treatment, it shrinks by about 25%.
In the end, the diameter of the case is 48.40 mm and the height is 17.77 mm. Once the element is sintered at a very high temperature, the ceramic solidifies, making the case very hard and therefore more difficult to use. The material becomes very resistant to scratches and corrosion, which means that surface treatment requires excellent expertise.
From polishing to linear or circular satin finishes, these finishes refine the outline of the timepiece, perfecting it in the true Greubel Forsey spirit. The dark blue ceramic brings subtle sparkle to the Double Tourbillon 30° technology, while its physical properties make it extremely resistant. The blue ceramic case and sapphire movement exude countless colors, surface treatments and textures. reviews aaa watches
It is equipped with a blue rubber strap, and is equipped with a titanium folding clasp, and decorated with hand-engraved Greubel Forsey logo. The crown-also ceramic-has the Greubel Forsey logo engraved on the tone.
